Ginkgo biloba has many uses such as edible, medicinal, and wood, and it is also an excellent tree species for greening and beautification. It has good ecological, economic, and social benefits, and its fruit, leaves, skin, branches, roots, and stems can all be used. According to different cultivation purposes, Ginkgo biloba has the following main planting modes:
1. The construction of seedlings for dwarf dense planting and high-yielding gardens should use 2-3 year seedlings for planting and planting in the year or the second year of planting. The initial planting density is 23 meters, that is, 110 plants/mu, and the pumped plants are removed before closure. The operating density is 46 meters, that is, 28 plants/mu, and the male to female ratio is 100:2-5. The male plants are planted above the perennial main wind direction.
2. Qiaogan sparse and productive gardens should generally use seedlings aged 4-5 years. For the Qiaoganfeng Production Park with a dry height of 100-150cm, the operating density is 56m, ie 22 plants/mu, and for the Qiaogan plantation more than 2m dry, the operating density is 67m, ie 15 plants. / Mu is appropriate.
3. It is advisable to create seedlings for the leaf collection garden with 2-3 years of age and a ground diameter of 1.5 cm or more. The planting density is 40100 cm apart. That is, 1666 strains/mu, so that a certain yield can be formed after 2-3 years of planting.
4. The seedlings for fast-growing and high-yield forests are 3-4 years old. The planting density is 45 meters.
5. Planting on all sides: The planting of Ginkgo biloba on four sides should be suitable for large seedlings. The distance between the planted Ginkgo biloba and the house should be no less than 3 meters, and the spacing between rows of plants should be 6-8 meters.
6. The establishment of farmland shelterbelt generally requires seedling age over 5 years, DBH 3.0 cm, seedling height above 2.5 meters, full-filled top buds, obvious apical dominance, and high-quality seedlings with well-developed root systems. Plants were planted at a distance of 6-8 meters in a single row and 8 meters in a double row with a spacing of 6 meters.
All kinds of planting patterns must be "deep hole, full fat, shallow planting, practical". Generally, the area south of the Yangtze River should be planted in September-November, and the northern area should be planted before and after spring clearing.
